Aluminium alloy Negative Pressure Direct Drive Fan 1100W For Ventilation
Ventilation and cooling principle:
Turn on the horizontal negative pressure fan system and longitudinal negative pressure fan system, make the indoor air flow and emit to the outdoors, after running for a period of time, the overall temperature of the indoor air to get a certain degree of reduction.
1. Less investment, low energy consumption. The same refrigeration
rate, a one-time investment of about one-sixth of the air
conditioning, operating costs of about one-tenth of the air
conditioning;
2. Cooling effect is remarkable, the temperature can be reduced to
about 28 degrees, consistent with the human body temperature, if
the water with the water wells as a source of water tanks better,
can be compared to the effect of air conditioning;
3. Air is fresh and moist, air cleanliness up to 99 per cent.
A.One-time stamping U-shaped fan blade, in line with the principle
of aerodynamics, toughness, strength, strong wind power and more
energy-saving.
B.Thickened galvanised non-flowering plate, not easy to rust and
corrode, stable operation.
C.Large air volume from high-power pure copper motor high-speed
operation, stable and not afraid of vibration.
D.High-speed rotor with ball bearings, strong performance, low
noise, thicker coils, safe and durable.
